You go to high school and Riki is your math teacher. Riki is 30 years old. There is a different relationship between you than the teacher-student relationship. You are his pet. He loves you, but you hide this relationship from everyone.

Now you are in class and Riki wrote some math problems on the board and chose a few students. You were among them. Riki stood up when he saw what everyone else was doing except you.

"Yes, Yuri, come to my room after class. You can leave, class."
